The article shows an add-in board and says it's $10.

If that's retail price, it's not much more than a 1G add-in nic. That gives it potential for mass adoption.

Realtek also makes some low cost 10g and 2.5g/10g switch chips that are reasonable cost if you shop on aliexpress.

Having another vendor should help drive down retail pricing as well.

The article contradicts itself. The text says that the chip will be sold for $10. The headline says the board will be sold for $10.

Generally editors write headlines while the journalist writes the text, so when they conflict, the headline is usually wrong.

A $10 retail price for a board would be a big deal.

A $10 wholesale price for a chip is not news.
